Prisma Fluorocarbon Tippet is used to tie discreet, dense leaders for subsurface fishing. Its fluorocarbon material sinks more naturally than nylon and is suitable for nymphs, wet flies, or streamers, depending on the chosen diameter. The special coating makes tying knots easier and provides a bit more elasticity than very stiff fluorocarbon. The X-sized options are ideal for delicate trout fishing, while the millimeter-sized diameters are suited for sturdier rigs. The choice depends on the diameter, strength, and required spool length.
